Calculating the integral by just cutting the paper and weighing it is hilariously clever. Bravo
-
The fact that you weighed the graph instead of doing a ton of math is amazing.
-
I haven’t watched Cody in years. The fact that he’s still wearing the chain mail makes me so happy
-
Making a rocket out of spare parts in a cave. Absolute legend.
-
From an engineer- weighing the paper of the area below the curve of the graph and then taking into account the per-square weight of the paper is one of the most ingenius methods of doing a definite integral that I have ever seen. The rocket is an extremely cool idea, but I'm almost too distracted by that wonderful old school integration technique to appreciate the rocket.

The best of OG YouTube. Rusty metal, cracked containers, duct tape all over, dodgy camera work... what more could we want? So happy Cody's still going strong!

I worked in a pesticide research lab in the 70's, and we used the same weigh-the-paper method to calculate the parts-per-million (or billion) of whatever pesticide we were testing for. We had a PDP-11 and a PDP-12 available to us, but weighing the paper was easier, and just as accurate.

So good to see cody back in good spirits. Seems like he got a new helper
-
Cody still being active makes me so fucking happy. Thankyou for years of great organic content :D
-
my man cody has been through some rough shit and still to this day has never dropped effort or quality in videos, he will always be one of the few old youtube legends
-
It’s been years since I’ve watched Cody‘s lab. Something I used to watch daily and I got immense pleasure out of this. It’s good to see you’re doing well man.
-
I should add, Cody is a bright and intelligent man - being able to muddle these projects together on a budget is inspiring.
-
weighing the paper was a clever idea, but subtracting the negative piece by using it to tare the scales was a stroke of genius. you truly have the mind of an engineer
-
Watching Cody build things from random pipe pieces makes me feel like I'm on a watch list
-
Hey that’s me! Thanks for the autograph Cody!!
-
Although somewhat dangerous in atmosphere, this would be an amazingly good idea for galactic fuel. In the vacuum of space it becomes a very stable and renewable resource that can easily be shaped for various purposes
-
Cody, for flying rockets there’s what’s called the Amateur Exception in the FAA regulations and people regularly build large metallic VTVL and ascending liquid (sometimes hybrid) rockets and fly them. At Black Rock in Nevada the airspace is under a quirky uncontrolled category where the paperwork is particularly easy. The folks at Friends of Amateur Rocketry site in California are great supporters and a launch site as well.

That worked way better than I thought it would! I figured you would have melting problems. I wonder if it would be better to inject both the water and the sodium as a liquid. Or you could fiber reinforce the sodium with something like steel wool. In any case I'm interested to see more!
-
i love how even after not watching for ~3 years the vibes of the channel haven't changed one bit
-
The rocket design looks like something from Fallout. I'd like to see this done with a reaction chamber and a pressure chamber, then the nozzle. Thank you for the video, this was fun!
